7 HAND OPERATE]? PRINTING PRESS I Filed June 26, 1928 3 Sheets-Sheet 5 Patented July 15, 1930- waste res PATEN ric DONALD AFELEGK ASPINALL, F 'EWIGKENHAM, ENGLAND HAND-OPERATED PRINTING PRESS Application filed June 26, 1928, Serial No.

printing press embodying a sheet metal struc ture including a base, a bed, an inking plate and a platen characterized in that the base is constituted by an inverted trough-like memher with outwardly facing attachment flanges, the bed by a sheet metal plate resting on top of the base, the inking plate by any extension of the bed, and the platen by a plate hingedly connected to the rear end-of the combined bed and inking plate,-the base having side plates attachedthereto cooperating with the bed to provide a chase receiving recess.

'Gther features of the invention consist in the means and manner in which the platen is operated, the chase is inked, and pressure applied 1 en printing.

A practical embodiment of the invention is illustrated by the accompanying sheet of dra gs, wherein I- v figure 1 is a side view of the press in its closed position. p 1

Figure 2 is a top plan view thereof.

Figure 8 is a vertical transverse sectional view of said press.

in carrying out the invention and referring to the drawings, the press consists of a base, of convenient length, constituted by an inverted trough-like member 1, of sheet-metal, with outwardly facing flanges 2 for attachment to a bench or the like, and at its front end provided with a vertically disposed extension 3 of convenient length, and on the horizontal top of said base is mounted a combined bed and inking plate. 1

The combined bed and inking plate is constituted by a length of sheet-metal, of convenient width, which, at a convenient distance from its upwardly bent rear end at, is, at 5, bent upwardly at right angles and then, at a c llVQlllGllb distance from said bend, is bent downwardly and forwardly at right angles, to form a horizontally disposed flat 288,356, and in Great Britain July 1, 1927.

plate 6, which rests on the vertical extension at the front end of the base 1 aforesaid, and that portion 7 of the sheet, between the rear and front bends a and 5 thereof, is, at each longitudinal edge, bounded by longitudinal and vertically disposed sheet-metal side plates 8 affixed to the side of the base 1, thus forming a rectangular recess or bed for the reception therein of a chase 9, whilst the horizontally disposed portion of the plate 6 in' front of said recess or bed 7 serves to receive ink thereon and the passage thereover of an inking roller 10.

To the upwardly extending rear end of the bed there is hingedly connected the platen, which is fitted with the usual spring-controlled grippers, said platen consisting of a sheet 11 of metal, of a size such as to cover over the bed 7 aforesaid, prov1ded on its upper face with an inverted trough-shaped sheet-metal member 12, said'bed resting on a stiiiening member 1.

in the front part of the trough-shaped member 12 aforesaid the rear ends of two oppositely disposed rods 13 are pivotally mounted, and between the front ends of said rods 13 and extending across the inking plate 6 there is rotatably mounted the inking roller 10, the same, at each end, being formed with a flange let which takes against a longitudinal edge of the inking plate 6, the length of said rod 13 being such that when the platen 11 is down, the roller is positioned at the front end of said inking plate 6.

To the trough-member 12 of theplaten 11 there is affixed by its short arm, an L- haped bar 15 whose long arm extends horizontally and backwardly over the trouglrmember 12 of the platen 11, and terminates in a hook 16 in which reststhe handle 17 carried by a cam 18 pivotally mounted on a. transverse and horizontally disposed rod 19 to each end of which is connected the upper end of an arm 20 which, by its lower end, is connected to a horizontally disposed shaft 21 which extends transversely through the base member 1 of the press.

In use, the platen 11 is raised by pulling backwardly the handle 17 of the cam 18 against the hook 16 of the L-shaped bar 15 with the result that said platen l1 swings on its pivots upwardly and backwardly, and at the same time, the platen 11, through the rods 13 connected thereto and the inking rollor 10, pulls back said inking roller 10 along the inking plate 6 on to and along the form in the chase 9, thus inking said form.

The paper to be printed on is now placed on the platen 11 and between the same and the grippers 22 thereof, and the platen 11 is then swung over, down on to the chase 9, the roller 10 at the same time, by its rods 13 aforesaid, being traversed back again over the form and alon the inking plate 6 to the front end thereoi The handled cam 18, and with it the arms 20carrying the same, is now swung forward to a position above the trough-member 12 of the platen, and the cam 18 is then turned by means of its handle 17 to bring its'cam face on to the top surface 23 of said trough-member 12 to exert pressure thereon, and consequently through the platen, forcing the paper carried thereby on to the inked form, after which cam pressure is released and the platen is again raised and the printed paper removed, and so on.

I claim e 1. A hand operated printing press comprising a base having side flanges rising above the top thereof, a bed plate resting on top of said base between said side flanges, upward extensions at the ends of said bed cooperating with said side flanges to form a chase receiving, recess inking means, and a platen for cooperation with a chase positioned in said recess.

2. A hand operated printing )ress comprisin a base, means for supporting a chase on sai base, a platen for cooperation with a chase supported on said base, an arm pivoted to the base, a lever pivoted to said arm, and a cam fixed with respect to said lever for press ing the platen in the direction of the chase by swinging movement of said lever.

3. A hand operated printing press comprising a base, means for supporting a chase on top of said base, a horizontally disposed inking plate extending outwardly from one end of said base, a platen hinged at the other end of said base for swinging movement into and from a position in overlying relation to the chase, an arm pivoted to said platen, and a roller carried by said arm for travel over said inking plate and over the chase.

4. A hand operated printing press comprising a base, means for supporting a chase on top of said base, a horizontally disposed inking plate extending outwardly from one end of said base, a platen hinged at the other end of said base for swinging movement into and from a position in overlying relation to the chase, an arm pivoted to said platen, a roller carried by said arm for travel over said inking plate and over the chase, an arm one end to the other of sai pivoted to the base, a lever pivoted to said arm, and a cam rigid with said lever for pressing the platen upon the chase by swinging movement of said lever.

5. A hand operated printing press comprising a base, side plates rising from the sides of said base, a bed late resting on top of said base between said side plates, said bed plate bein extended upwardly at the ends of said sidh plates for cooperation with the latter to provide a chase receiving recess, an inking plate extending horizontally from the upper end of one of the u ward extensions of said bed plate, a laten hinged at upward extensions of said bed plate, an arm pivoted to said platen, an inking roller carried by said arm for movement over said inking plate and the chase by swinging movement of the platen, an arm pivoted to the base and a lever pivoted to said last mentioned arm and carrying a cam for cooperation with the platen to press same upon the chase by swinging movement of said lever.

6. A hand operated printed press comprising a base, means for supporting a chase thereon, a platen hinged for swinging move ment to and from a position in overl ing relation to a chase supported on the ase, an arm pivoted to the base, a lever pivoted to said arm, a cam carried by said lever for cooperation with said platen to press same in the direction of a chase supported on the base, said lever being swingable with said arm'to a position to permit said platen to be swung upwardly from the chase, and a member carried by the platen having a stop for engagement by said lever whereby swinging movement of the latter with said arm is effective to swing the platen upwardly from the chase.

In testimony whereof I have afiixed my signature hereto this 15th day of June, 1928.
